I have a sick looking bougainvillea, the leaves are yellowing and small. It is growing in poor soil in front of tanalised retaining posts for a few years, previously a good display. I have given it blood and bone, rooster booster and recently thrive and a product called vege grow purchased from Rogers, but not all at once. My last bougainvillea took sick and died In a similar position. Could it be poisoning from the retaining posts?
If so, does it mean all planting there would not thrive?
I recently planted spanish, ficus pimula and chinocloa there, will they survive?
Please advise thank you!

Hi Rose

Thank you for your question. Bougainvillea will produce at it’s best with very little care. I am wondering if the history of feeding (even if not all at once) over such a few years has actually causing the problem. Treated timber will not affect it but overwatering since they are a hot loving plant can cause problems too. Try watering less and ceasing any feeding to see if your plant perks up.

Happy gardening
